@nicht I IMPROVED ELEITATING' AND WEIG-HING-APPARATUS.

The Schedule referred to in these Letters Patent and making pan of thesame.

To all whom fit may concern:

Be it known that I, J AMES EL BRooKMIRE, of St. Louis, inthe county ofSt. Louis, and State of Missouri, have 'made certain new and usefulImprovements in Elevators and Scales; and I do hereby declare that thefollowing is a full and clear descliption thereof, reference being hadto the accompanying drawings, .and to the letters of reference markedthereon.

."The nature of this invention is in the arrangement ofthe usual form ofgoods or iieiglit-elevator', or hoisting-apparatus, in such wise thatthe goods or freight placed upon the platform may be weighed whilethereon; and

The nature of this invention is also in the manner of connecting andadapting the parts of the ordinary form of hoisting-platform with theparts of a scale, so as to effect the purpose before stated, all 'ofwhich will hereinafter be more fully set forth.

To enable those skilled herein to make and use my said invention, I willdescribe the same, referring to `.the accompanying Figure l asa frontelevation;

Figure 2 as a transverse sectional elevation; and "Figure 3 as asectional plan.

I alrange the usual side guide A, which will generally be supportedagainst the floors of a building, and within the said guide I arrangethe elevator B, having the platform B connected with the side frame Cand upper cross-beamD.

The hoisting-rope E will pass through the crossbeam D, or, attaghingV tothe lift-holt F, this bolt will pass through said Beam;

Owing to the arrangement of the scale, in connection with my saidelevating-platform, it is advisable to reduce the ,ja-rand concussion,caused by rolling goods on or o the platform B, by using a spring, F',under the bolt F, toconnect the lift-bolt and hoisting-rope with thecross-beam l). Said spring will also serve yas an integral part of thesafety-latch formed by the bell-crankl levers G, which. are pivoted at9,011 the side framevO, and connect with the bolt F.

'The ends of the levers G pass through the frame O, and may engage onthe teeth of the racks H, which are secured to the guides A.

If the spring F is released by breakage of the rope' E or bolt F, thenits pressure is exerted to cause the ends of the levers G to engage on'the racks H, and

ythus support the platform and its load, as in the ordinarysafety-latches.

In order that goods, when placed upon the platform B', maybe weighedwhile thereon, as in the nature of this invention, I have arranged,within the outer frame B of said platform, the inner-platform plate B2,upon which freight will rest. Said plate Bl is the platform of a scale,of any construction desired, resting upon ports on the exterior frame B.

the usual supports and scale -levers, by which the weight of the freight(and platform) is carried to the lift-bar I. Said lift-bar, I arrange inthe 4'side frame G, making the latter hollow for this purpose.

The lift-bar I then connects with the scale-beam K, arranged withweights, k, andfulcrum, and such other parts and connections as areneeded to cause the scale-beam and weights la to indicate the weight offreight on the platform-plate B2, the said devices for weighing beingconstructed in the 'general manner usual in common platform or otherscales.

Whenever the operation of weighing is not being performed, the` lever Lwill be released from the hook I, and the scale-beam K and lift-bar Iwill then lower, so as to permit the platform B2 to rest on propersuprIhis support of the platform B2 is especially desirable in ,loadingand unoading freight. l

The materials of which the parts of my said elevator and scale are made,are the ones usually employed, and the proportions and dimensions of theparts such as any competent mechanics may devise.

I do in nowise limit myself to the special form of attaching thescale-beam K, at the side of theframepiece C, as said attachment may bevaried; neither are the forms of the partsl essential to the nature ofthis invention; but said nature includes all such arrangements and formsas might arise in the Acombination of an elevator-platform, orelevator-frame and a scale.

Moreover, in certain forms of my said invention, a

platform, B B2, would not be necessary. Thus, in a goods-hoist, by ahoistingrope,ordinary steelyards are to be connected with'thehoisting-rope. In this wise, a travelling scale is achieved, the generalprinciple whereof is essentiallyincluded in the nature of thisinvention.

The said elevator, when resting at each floor of a building orwarehouse, serves as a scale for the said door and story, and thus an.economy iu the number of weighingdevicesis achieved, whilst, as togoods being shipped from story to story, a saving of handling isachieved by 'weighing on the elevator-scale.

Having thus fully described my said invention,

What I clai1n,is-

'lhe platform B B2 and side frame O, cross-bar D and lifting rope E,when combined with the scaleworks, and lift-bar I, and scale-beam K,substantially as set forth. 1

In witness of said invention, I have hereunto set my hand, in thepresence of JAS. H. BROOKMIRE.
